MSPRO said:Having turbo'd a B15 before I bought the MSP I would highly suggest not picking a b15 chasis to build. They are the most complicated b.c they have the new roller rocker engines and even though stuff boltsup they are harder to tune. I had an SAFC for tuning and it was ok but everything is more complicated in a b15. Most of the turbo B15's I know out there switched the entire wiring harness out with a b14 so that they could use the JWT ECU's and what not..Also its not easy to do drop in of a bluebird/avanier engine b.c of the difference in wiring and other little things.. I am just speaking from experience about the platform... It can be done but it is not the easiest..
B13 Sentra's with the bluebird are money in the bank.
